/* site/src/assets/css/page-careers.css
 * Careers: not hiring, still listening.
 *
 * The page's one idea is a receiver. Nothing is being broadcast — there is no
 * vacancy — but the set is on, and tuning across the band brings up one thing
 * the studio would want in a person, until the last station, which is dead
 * air and says so.
 *
 * It is built from six radio buttons and :has(). A radio group is already a
 * dial: the arrow keys tune it, the tab key reaches it, and there is no
 * script to fail on a slow connection. Nothing here loops on its own, so
 * there is no animation to pause when the tab goes away — every movement is
 * a transition somebody asked for.
 *
 * Where :has() is missing the dial hides itself and the six stations fall
 * back to an ordinary readable list. That is why the tuning lives inside the
 * @supports block and the plain state lives outside it.
